When #if DEBUG runs

Question

I have this code in my C# class.

#if DEBUG
        private const string BASE_URL = \"http://www.a.com/\";
#else
        private const string BASE_URL = \"h         


        

Answer 1

#if DEBUG It's a preprocessor definition.

It compiles when you define DEBUG constant. And yes, it's default on Debug Build Configuration.

Visual Studio 2010 Project Properties:

If Define DEBUG constant is checked VS will compile:

private const string BASE_URL = "http://www.a.com/";

Else (not checked) VS will compile:

private const string BASE_URL = "http://www.b.com//";
